Specification of Letter Patent.

Application led May 5, 1919. Serial No. 294,657.

To all "107mm t may concern.'

Be it known that I, VILLIAM K. AUCHIN- oLoss, residing at 569 West Endavenue, New York, N. Y., and being a citizen of the United States, haveinvented certain new and useful Improvements in Tank-Anchors forTank-Cars, of which the following is a full clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and to use the same, reference being had to theaccompanying drawings; which illustrate the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details 'of construction shown and described, as itis obvious that various modifications thereof. within the scope. of theclaims will occur to persons skilled in the art..

In said drawings:

Figure 1 is a transverse sectional view taken through a fragment of thebottom sheet of' the tank of a tank car and transversely through thecenter sills,v showing in end elevation the anchoring means forming thesubject matter of this application;

Fig. 2 is a fragmentary side elevational view showing at the upper partin section a fragment of the bottom sheet of a tank, and at the theupper portion ofthe center sill with the anchoring means shown inelevation and partly broken away for purposes of illustration.

`The object of the invention is to secure in a tank car a low center ofgravity, to provide tank anchoring means permanentlysecured,respectively,'to the tank and to the center sill, whichanchoring means are so disposed with relation to each other that theassembly of the parts is conveniently arranged so as to permit drivingmachine driven rivets to secure the anchorto the sills or underframe theanchor is connected, and to the tank.

Referring to the parts, 2)*3 indicate the center sills of an ordinarytank car underf'rame, which sills are ordinarily spaced a convenientdistance apart and in the present instance are connected by means of atransversely disposed top sill cover plate 4, which cover plate ispreferably of a single sheet entire length of the anchor and is securedto the top flanges ofthe sills by rivets 5, which "rivets may 'areadapted to secure the bottom of the view a fragment of member of the carwith which" be machine driven before the tank is placed 1n position, dueto the space surrounding the rivets, which will permit application ofthe rivet heading means commonly used.

he cover plate 4 or equivalent transversely extending member connectingthe sills has angular extensions (3-6 which, as will be noted, arebeyond the top flanges 7 of the center sills and are spaced somedistance therefrom.

The flanges 6 are perforated to receive the connecting rivetshereinafter referred to,

Secured to the bottom sheet 8 of the tank is a pair of tank anchoringmembers which tanks to the underframe and. these members consist each ofa sheet of metal 9 which is formed at its middle portion l0 of a.channel shape, as best shown in Fig. 1, and terminates in flanges 11 and12, which flanges are angularly disposed withrelation to each other, theflanges 11 comprising an upwardly curved portion which extends from themiddle channel portion. This upwardly curved portion is of a curvaturecorresponding to the contour of the bottom sheet 8 of the tankto whichit is permanently secured by means of the inachine driven rivets 13, andit is to be noted that the rivets 13 should be driven by chinery becausetheyare subjected to 'great stresses in bufling and pulling, whichstresses would, under service conditions, tend to rupture an imperfectlconnection of the flanges 11 with the bottom sheet of the tank,

An added advantage in a machine driven rivet at this point is that suchrivets can be driven with sufficient force to obviate the necessityforcalking, something which is quite important in tanks vof railway tankcars adapted to carry gasolene and other hydrocarbon fluids.

Intermediate the channel portion 10 of the anchor and the downwardly andoutwardly extending flanges thereof, is a shouldered portion 14, whichshoulder is of importance in that it provides a seat for the anchor,when the -parts are in assembled relation.

ln practice, the parts are assembled as follows: first, the cover plate4. or ccuimlent member, is connected by machine driven rivets to the topflanges 7 of the. center sills, with the flanges 6 depending downwardlyand outwardly as shown, the anchor inem. bers 9 are secured to thebottom sheet 8 of the tank by machine driven rivets, as indiafter whichthe rivets l5 may be drivenby y suitable rivet driving machine, and itis to be noted thatrwhile the space between the top cover plate 4 andthe bottom of the tank isonly about l in-. in an SOOO-gallon tank,

all of the rivets, due tothe disposition of the flanges indicated, maybe driven by machinery and when it is desired to remove the tank fromthe underfram'e, as for purposes of repair, the rivets may be cutwithout def struction of any part, except the rivets themselves, thetank removed, repaired. and replaced as before noted. v

What I claim is: I 1. In an anchor for the tank of a railway tank-car,spaced center sills having upper flanges, a cover-plate connected withsaid flanges and having lateral extensions projecting outwardly anddownwardly therefrom, a tank and anchoring means therefor secured to thetank and lapping said cover plate extensions.

2. In an anchor for the tank of a railway tank-car, spaced center sillshavinr. upper flanges, a cover-plate connected with said flanges andhaving lateral extensions projecting outwardly and downwardly therefrom,and anchoring means for a tank lapping the said outward and downwardextensions, riveted thereto and also extending tank.

8. In an anchor for the tank of a railway tank-car, spaced center sillshaving upper flanges, a member spanningsaid sills and having yextensionsprojecting below the top plane of said sills, a tank and anchoring meansfor 'the tank secured thereto and lapping said extensions.

4. In an anchor for the tank of a railway tank-car, spaced center sills,a transversely extending member connecting said sills and to each other,one of said flanges extending upwardly and outwardly and one of saiflanges' extending outwardly from said middle portion and thencedownwardly and both flanges being perforated.

6. As an article of manufacture, a tank anchor adapted to secure thetanks of railway tank cars to a car underframe member and consisting ofa shouldered middle portion adaptedto rest upon such underframe memberand terminating in flanges angularly disposed with relation to eachother, One. of said flanges being ada ted to form a seat for the tankandone o said flanges 'being adapted to extend below, said shoulderedportion for connectionwith said member.

In witness. whereof .I have hereunto set my hand in the presence of twowitnesses. upwardly and outwardly to fit the shell of a l f WILLIAM K..AUCHINCLOSS.
